NECK-YOKIE AND POLE-CAP.

Specification of Letters latent.

Patented Apr. 23, 1918.

To all whom it may concern:

Be it known that I, GUs'r YOUNG, a citizen of the United States, residing at Mora, in the county of Kanabee and State of Minnesota, have invented certain new and useful Improvements in Neck-Yokes and Pole- Gaps; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to neck yokes and pole caps and is in the nature of an improvement on my U. S. Letters Patent, 1,063,759, issued to me June 3, 1913, and entitled Neck yoke.

To the above end, generally stated, the invention consists of the novel devices and combinations of devices hereinafter described and defined in the claims.

In the accompanying drawings, which illustrate the invention, like characters inclicate like parts throughout the several views.

Referring to the drawings,

Figure 1 is a view in side elevation of the free end portion of a vehicle pole to which is applied the improved pole cap and neck yoke, said neck yoke being shown in central vertical section;

Fig. 2 is a plan view of the parts shown in Fig. 1, with the exception thatthe neck yoke is removed;

Fig. 3 is a front elevation of the neck yoke;

Fig. 4 is a plan view of the same;

Fig. 5 is a transverse vertical section taken on the line 5'5 of Fig}. 3; and i Fig. 6 is a detail view in section taken on the line 66 of Fig. 1, on an enlarged scale.

The numeral 7 indicates a wagon pole having a pole cap 8 in the form of a strap extending over the upper and lower surfaces of said pole and rigidly bolted thereto. At the tip of the pole 7, the cap 8 is bent outwardly and downwardly therefrom to form a loop 9 to which may be applied a hook or clevis, not shown, for the purpose of attaching a lead team to the pole. The strap forming the pole cap 8 is also bent to form upper and lower stop shoulders 10. To these upper and lower stop shoulders 10, are applied. respectively, wearing cheeks 11 and 12, preferably in the form of malleable or steel castings. These wearing cheeks 11 and 12 have side flanges which receive the stop shoulders and are adapted to be upset onto the backs thereof, for the purpose of securing the wearing cheeks thereto. An upwardly projecting stop finger 13 is integrally formed with the wearing cheek 11 and an integrally formed lug 1 1 projects forwardly from the upper end of the wearing cheek 19., bears directly on the pole cap 8 and is secured to the pole 7 by a screw or otherwise. Pivoted to the upper stop shoulder 10 for vertical swinging movement, is a hook 115 through the eye of which the stop finger 13 projects and limits the lifting movement of the hook 15 from the pole cap 8. This hook 15 may be either formed from sheet metal or casting and a leaf spring 16 yieldingly holds the same in contact with the pole cap 8.

The neck yoke is made up of upper, lower and intermediate longitudinal members or rods 17, 18 and 19, respectively, the outer extremities of which are brought together, surrounded by bands 20 and rigidly con nected by welding or other means. Outward of the bands 20, the ends of the neck yoke are provided with elongated eyes 21 in which are secured rings 22 provided to receive the hame straps. At the central portions of the neck yoke members '17 and 18, the same are curved upwardly and downwardly, respectively, to form a passageway 23 for the pole cap 8. The intermediate portion of the neck yoke member 19 is bent horizontally outward to form a truss for the members 17 and 18. On each side of the pole passageway 23, the three members 17, 18 and 19 are rigidly connected by struts 24,, as best shown in Fig. 5. To further strengthen the neck yoke members 17, 18 and 19, and holding the same in triangular arrangement the same are rigidly connected by tie straps 25 located intermediately of the pole passageway 23, and the ends of the neck yoke.

The neck yoke, at the pole passageway 23, is reinforced by channel bridge bars 26 in which the members 17 and 18'are mounted at their central portions. These bridge bars 26 extend slightly outward of the struts 24- with their flanges projecting toward the truss rod 19 and bent or folded onto the members 17 and 18 to hold the same in position thereon, as best shown in Fig. 5. To further assist in securing the bridge bars 26 to the members 17 and 18, the same are provided outward of the pole passageway 23 with integral lips 27 that are also upset onto said members. Struts 28 rigidly connect the bridge bars 26 outward of the pole passageway 23 and are preferably integrally formed therewith. As shown in Fig. 1, the bridge bars 26 bear directly on the wearing cheeks 11 and 12. Preferably, the struts 24, bridge bars 26 and struts 28 are stamped from sheet metal. The neck yoke member 19 not only forms a truss for the members 17 and 18, but projects outward of the tip of the pole cap 8 and afiords a guard to prevent the reins from catching on the pole cap.

As is well known, a great many runaways have been caused by the reins catching on the pole outward of the neck yoke and also by the pole cap becoming detached from the neck yoke, in case one or more of the traces become detached from the whiflletrees. The hook 15 will, of course, prevent this latter cause. Primarily, the stop finger 13 is straight, but after having been inserted through the eye of the hook 15, it is upset, at the proper angle, to prevent the hook 15 from lifting from the pole cap 8, only sufficiently to allow the neck yoke member 17 to pass thereunder. Hold-back straps may be placed around the bands 20 and are held against undue sliding movement on the neck yoke by the elongated eyes 21 and the diverging members 17 and 18.

It is, of course, understood that the neck yoke members 17, 18 and 19 may be either of solid or tubular form and the pole cap 8 is preferably formed from commercial stra iron.

What I claim is 1. A neck yoke comprising upper, lower and intermediate members rigidly connected at their extremities, said upper and lower members being centrally spaced to form a pole passage and said intermediate member being extended horizontally outward to form a truss for the other of said members, struts connecting said three members on each side of thepole passage, and channel bridge bars receiving and reinforcing said upper and lower members at the pole passage, the flanges of said bridge bars being upset onto said upper and lower members to secure the same thereto.

2. A neck yoke comprising upper, lower and intermediate members rigidly connected at their extremities, said upper and lower members being centrally spaced to form a pole passage and said intermediate member being extended horizontally outward to form a truss for the other of said members, struts connecting said three members on each side of the pole passage, chan nel bridge bars receiving and reinforcing said upper and lower members at the pole passage, and struts connecting said bridge bars on each side of the pole passage.

3. A neck yoke comprising upper, lower and intermediate members rigidly connected at their extremities, said upper and lower members being centrally spaced to form a pole passage and said intern'lediate member being extended horizontally outward of the pole cap to form a truss for the other of said members and a guard for said pole cap, said intermediate member being free to move above or below the pole cap, and struts connecting said three members on each side of the pole passage.

4. A neck yoke comprising upper, lower and intermediate members rigidly connected at their extren'iities, said upper and lower members being centrally spaced to form a pole passage and said intermediate member being extended horizontally outward to form a truss for the other of said members, struts connecting said three members on each side of the pole passage, and an integrally formed reinforcing bracket applied to the said upper and lower members at the pole passage and transversely connecting the same.

In testimony whereof I aflix my signature in presence of two witnesses.

GUST YOUNG.
